Question

Complete the square to determine the minimum or maximum value of the function the expression defines. x2 − 38x + 9 A) maximum value at 361 B) minimum value at −352 C) maximum value at −352 D) minimum value at −361

Answer 1

minimum value at −352

Explanation:

First, set the expression equal to 0.

x2 − 38x + 9 = 0

Complete the square.

x2 − 38x = −9

x2 − 38x + 361 = 352

(x − 19)2 − 352 = 0

Therefore, the minimum value is −352.
